Ancestry dna test info?

Hi I live in uk and would like to take an ancestry test to determine if my nan was of any Japanese extraction,also to see if there is any European in me. Which is the best site to order my kit from who actually are able to do this? I don't want a whole list if possible I'd like it narrowed down to Japanese and any European. My family are ethnic Persians

    It is really what you are looking for and what type of DNA test you do.

    There are 4 types of DNA, 3 that are being tested for ancestry.

    Y is passed from father to son. It is a male sex chromosomes but about 1 out of 6 females get the Y.

    The reason they are the female phenotype is they are totally insensitive to testosterone and therefore they are totally estrogen. They will not have ovaries. They will not know about it until they go through puberty and fail to have a menstrual period. Then their physician will do tests. If you changed the diapers of a xy female it would be no different than if you changed the diapers of an xx female.

    X is the other sex chromosomes, both males and females get an X from their mother and in addition about 5 out of 6 females get an X from their father. The X has been regarded as untraceable. However it is being used in the Geno 2.0 test.

    Mitochondrial is in the cytoplasm outside the cells and is passed from mother to both sons and daughters but only the daughters pass it to the next generation.

    Autosomal you get 50-50 from both parents but not necessarily 25% from each of your 4 grandparents. The reason why what you inherited can be biased between grandmother and grandfather on both sides of the family. How you inherited any bias will not be how your siblings inherited it. An exception can be for identical twins.

    Y & Mitochondrial testing have been used for years as they both go back in a straight line unchanged barring mutations. How it is useful is if you find others you feel you might possibly share ancestors with in those 2 direct lines and if you are tested and have a complete match with them then you are in a position to share information. The Y is facilitated with surname projects. Now with each they will assign you to a Haplogroup and show you the origin of your nomadic ancestors going back thousands of years. However it is only in 2 lines, Your family lines double each generation you go back. If you can have both tested by the time you got back to your 16 great great grandparents, 14 of them will excluded from the results. So don't be fooled when they tell you they can show you your deep ancestral origins. It is only in 2 lines. Y & Mitochondrial are totally useless in giving a person an overall view of their ancestry. Understand that Y & Mitochondrial testing is very exact but represent a tiny part of your total ancestry.

    Most of your DNA is Autosomal. It is what is used in the overall ancestral testing. However Autosomal does not come down in a straight line unchanged. There are no Haplogroups with Autosomal. The problem is the only thing they can do is match you with population samples they have. Therefore it has been reported that if you have your Autosomal tested by more than one company the results will not be the same. No doubt that is because one might be deficient in or not have a certain population samples the other one does and vice versa. This type of testing has been over hyped on TV. Maury Povich doesn't know enough to ask questions to clear things up. If George Lopez and the other celebrities had theirs tested by other companies they will no no doubt get different results. It is not that DNA lies but it is a matter of what they have to analyze it by is not perfect.when it comes to the Autosomal tests. So anytime they give you a pie chart breaking down your ancestry keep some skepticism about you.

    Here is a short video on Autosomal. The audio quality is not the best but the text of the audio is at the bottom of video.

    A couple of websites to check out are FamilyTreeDNA and 23and me.

    Then there is DNATribes that only test Autosomal. What they do is show you your top 20 matches in descending order. They aren't saying you have ancestors from all those matches. They will give you additional matches for an additional fee. They have 1227 population samples and 918 Indigenous populations.

    Ask as many questions that you have in advance. You can do that easily with FamilyTreeDNA and DNATribes by going under "feedback" at the top by emailing them and asking questions. They are very prompt at replying before you take any tests and after you take the tests.

    Probably your best bet would be the Geno 2.0 test from National Geographic. This test will give you your deep ancestry with migration patterns and is considered the most accurate test to date. This test gives you your anthropological history rather than genealogical history.

  • Like dodos, Persians, Babylonians, et al are all extinct.

    Simple: go to www.familytreedna.com. It is the oldest such site, with the largest data base, they do the testing for the National Geographics Genotype Program which traces human migration patterns worldwide and is affiliated with the I.S.O.G.G. (www.isogg.org).
